An apparatus includes an external input device that allows setting of the amount of runout and the phase of each cutting edge, a computation device that acquires the rotational phase of a tool and that computes the angular velocity and the phase of vibration of two, X-axis and Y-axis, feed shafts on the basis of the input amount of runout and angular velocity of each cutting edge to generate a feed shaft control signal, and a numerical control device that controls feed in the X-axis and the Y-axis directions. The numerical control device relatively vibrates a workpiece in synchronization with the angular velocity of the tool on the basis of the results of computation performed by the computation device.
A machining vibration suppressing method for a machine tool that machines a workpiece while rotating a tool mounted to a main spindle, the method comprising:
A machining vibration suppressing apparatus for a machine tool that machines a workpiece while rotating a main spindle to which a tool having one or a plurality of cutting edges are mounted to feed at least one of the workpiece and the tool in a plane that is orthogonal to the main spindle, the apparatus comprising:
